In this DreamWorks animated tale, Oscar (Will Smith) is a small fish whose big aspirations often get him in trouble. Lenny (Jack Black) is a great white shark with a secret: He's a vegetarian. When a lie turns Oscar into an improbable hero and the truth about Lenny makes him an outcast, the two form an unlikely friendship -- much to the dismay of Lenny's mafioso dad (Robert De Niro). Angelina Jolie and Martin Scorsese also lend their voices.
